Squamata is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians, which are collectively known as squamates or scaled reptiles. With over 10,900 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the 16 mm (0.63 in) dwarf gecko to the 6.5 m (21 ft) Reticulated python and the now-extinct mosasaurs, which reached lengths over 14 m (46 ft).
Anguidae refers to a large and diverse family of lizards native to the Northern Hemisphere. Common characteristics of this group include a reduced supratemporal arch, striations on the medial faces of tooth crowns, osteoderms, and a lateral fold in the skin of most taxa. The group includes the slowworms, glass lizards, and alligator lizards, among others. The family is divided into three subfamilies, and contains about 100 species in 10 genera.

The prickly skink, or prickly forest skink, is a morphologically and genetically distinctive species of skink endemic to rainforests of the Wet Tropics of Queensland World Heritage Area, in north-eastern Australia. Unlike most small skinks, which have smooth scales, this species has rough, ridged and pointed scales. These keeled scales may be an adaptation to its high-rainfall habitat, to its microhabitat in rotting logs, or to camouflage it when moving through forest leaf-litter.
Amphibians of Australia are limited to members of the order Anura, commonly known as frogs. All Australian frogs are in the suborder Neobatrachia, also known as the modern frogs, which make up the largest proportion of extant frog species. About 230 of the 5,280 species of frog are native to Australia with 93% of them endemic. Compared with other continents, species diversity is low, and may be related to the climate of most of the Australian continent. There are two known invasive amphibians, the cane toad and the smooth newt.

These snakes appear to be blind, only having vestigial eyes that are extremely sensitive to light. It is a cryptic burrowing snake that lives in tunnels underground, living mainly on a diet of ants. They are found in arid and semi-arid desert regions of central Australia and are considered endangered in New South Wales (NSW).
Lucasium steindachneri, commonly called the box-patterned gecko or Steindachner's gecko, is a species of nocturnal, medium-sized lizard in the family Diplodactylidae. The species has a pale strip with three patches of brown along its back. This gecko is terrestrial and only found in arid and semi-arid areas of continental Australia.
